Coming from Kansas, I can say that a 2 vs 4 yr degree means very little, esp when it comes to financial decisions. All paramedic programs in Kansas have or are converting to a 2 year degree ( as a lot of them were certification programs in the past, this is a huge step for us). I work for the Federal Government as a GS-7 paramedic with a 2year degree, I make approx. $45,000 per year, same as I would make if I have a 4 year degree. This is probably the best paying job in the state. With time in grade I will probably max out at $60,000 per year.
Four year degree medics here trend toward management. Once you factor in the huge rural population here and the shortage of EMS personnel, you can begin to see why. Street time and a 4 year degree will get you a management position here because you are the best qualified due to lack of choice. Even in our more urban areas i.e. Topeka, Wichita, and Kansas City, many medics are of the 2 year degree type. How they progress I cant really say, but management postions there are a little harder to come by.
On a side not, if we are absorbed by the the fire dept. where I work, my 2 year degree will have me in a comparble salary bracket to several assistant directors/directors in the state.
This is just regular shift work with no overtime.
